Nepeta grandiflora &#39;Summer Magic&#39;

ABSTRACT

A new and distinct  Nepeta  cultivar named ‘SUMMER MAGIC’ is disclosed, characterized by plants with a compact, bushy habit and improved resistance to wind and rain damage. Flower stems have improved branch structure and plants produce a large quantity of flowers. The new cultivar is a  Nepeta,  suitable for ornamental garden purposes.

LATIN NAME OF THE GENUS AND SPECIES

Nepeta grandiflora

VARIETY DENOMINATION

‘SUMMER MAGIC’

BACKGROUND OF THE INVENTION

The new cultivar is a product of chance discovery by the inventor. This new variety, hereinafter referred to as ‘SUMMER MAGIC’, was discovered as a chance seedling by the inventor, Malcolm Spencer. The seed parent is believed to be Nepeta grandiflora ‘Bramdean’ , unpatented and the pollen parent undetermined. This interesting new variety was discovered in the inventor's garden during June 2010 as an individual seedling plant. The plant was discovered in West Sussex, England.

After identifying the new variety as a potentially interesting selection, the inventor first propagated ‘SUMMER MAGIC’ by vegetative cuttings during July of 2010, at his home in West Sussex. England. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. Subsequently, several generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SUMMER MAGIC’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SUMMER MAGIC’ These characteristics in combination distinguish ‘SUMMER MAGIC’ as a new and distinct Nepeta cultivar:

-   1. Compact bushy habit -   2. Improved branch structure on flower stems -   3. Improved plant sturdiness; better resistance to wind/rain damage -   4. Distinctive strong flower color -   5. Large quantity of flowers

COMPARISON TO PARENT VARIETY

‘SUMMER MAGIC’ is similar in most horticultural characteristics to the presumed seed parent variety Nepeta grandiflora ‘Bramdean’. Plants of the new cultivar ‘SUMMER MAGIC’ however, differ in the following:

-   1. The new variety is shorter -   2. The new variety produces more branches. -   3. The new variety has improved resistance to weather damage—parent     variety is often broken open by summer storms.

COMMERCIAL COMPARISON

‘SUMMER MAGIC’ can be compared to the well known commercial variety Nepeta faassenii ‘Six Hills Giant’, unpatented. Plants of the new cultivar ‘SUMMER MAGIC’ are similar to plants of ‘Six Hills Giant’ in most horticultural characteristics. Plants of the new cultivar ‘SUMMER MAGIC’ however, differ in the following characteristics:

-   1. The new variety is much shorter -   2. The new variety has significantly improved branching on flower     stems -   3. The new variety has improved resistance to weather damage -   4. Pinching requirements and or/growth regulator use are eliminated     are reduced to produce plants for garden center sales.

‘SUMMER MAGIC’ can be compared to the known commercial variety Nepeta racemosa ‘Little Titch’, unpatented. Plants of the new cultivar ‘SUMMER MAGIC’ are similar to plants of ‘Little Titch’ in most horticultural characteristics. Plants of the new cultivar ‘SUMMER MAGIC’ however, differ in the following characteristics:

-   1. The new variety produces longer flower spikes. -   2. The new variety produces more flowers per stem, and more     flowering stems per plant. -   3. The new variety has improved resistance to weather damage -   4. The new variety produces more branches per plant.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SUMMER MAGIC’ grown outdoors in West Sussex, England. The plant is approximately 1 year old, and is shown in a 2 liter container.

FIG. 2 shows a close up of several flowering spikes.

FIG. 3 illustrates in close up perspective a typical flowering spike. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
